Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Drug therapy and clinical monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Hematopoietic Stem Cell Transplantation
Allogeneic hematopoietic stem cell transplantation replaces defective osteoclast precursors with healthy donor cells, potentially curing the underlying bone remodeling defect in severe infantile osteopetrosis.
Calcitriol (Active Vitamin D3) Supplementation
High-dose calcitriol stimulates dormant osteoclasts to resume bone resorption activity, helping to normalize bone density over time.
Additional treatment options
Orthopedic Intervention for Fractures
Surgical management of pathological fractures using appropriate fixation techniques accounts for the increased bone density and altered healing patterns in osteopetrosis.
surgicalMultidisciplinary Surveillance Program
Comprehensive monitoring including regular neurological assessments, vision and hearing evaluations, endocrine function tests, and bone density measurements to detect and manage complications proactively.
monitoringRehabilitative Physical Therapy
Individualized exercise programs maintain joint mobility, prevent contractures, and support functional independence while avoiding activities that risk fractures.
